Be it lniown that I,- CLARK E, CMPP, e citizen-of the United States,residing et ,site J'o's lyintheeouuty of Buchanan and State of lilissouri, have'invented new and useful Improvements in Train-StoppingApparatas', of which the following 1s a specificetion. i

This, invention relates to improvements .in
